Force Lines: Omnidirectional Lines of Force:
“I spoke about Galileo’s parallelogram of forces where, you may remember, you had two moving bodies and you had their discrete angles and you have them running into each other. One weighs so much and has such and such a velocity-- multiplying both and making vectors, you drew two lines parallel to them with respect to where they intervened. Then you made the parallelogram and the diagonal of the parallelogram from the points of interception, extended it outwardly of the parallelogram, and call it equidistant, and call it the resultant of forces. I thought this was very strange because I was in the Navy, while this diagram tells me that when two ships run into each other at sea, they waltzed off 12 miles northwest with each other and that isn’t what they did at all. One seemed to go to the bottom and that wasn’t in the diagram. So I felt that it was really invalid to make models that really didn’t have to do with our physical Universe.”
